Test Example 1

Composition 2 above was treated with benzisothiazolinone (BIT) orunpreserved, and aged for four weeks at 40° C. and then sent formicrobial challenge testing.

Example 1 - Unpreserved - Aged for 4 weeks at 40° C. Example 2 - 200 ppmBIT Aged for 4 weeks at 40° C.

Procedure: Based on ASTM D2574

In-Container Preservative Effectiveness Testing & USP <51> AntimicrobialPreservative Effectiveness

The U.S. Pharmacopeia XXI <51> states effective preservation of theproduct if the following conditions are met: “(a) the concentrations ofviable bacteria are reduced to not more than 0.1% of the initialconcentrations by the 14^(th) day; (b) the concentrations of viableyeasts and molds remain at or below the initial concentrations duringthe first 14 days.

In order to prove the absence of microbiological contamination in theoriginal samples, negative controls were run at the beginning, middle,and end of the experiment to show that any growth observed occurred as aresult of the inoculation. Two separate challenges were performed: ATCCBacterial Pool, ATCC Fungal Pool. The single-inoculation 28 day protocolof USP <51> was enhanced with the addition of a second inoculation onDay 7 as seen in ASTM D2574 (In-Container Preservative EffectivenessTesting).

Bacterial Inoculum Pseudomonas aeruginosa ATCC 9027 Pool: Escherichiacoli ATCC 8739 Staphylococcus aureus ATCC 6538 Fungal Inoculum Candidaalbicans (Yeast) ATCC 10231 Pool: Aspergillus brasiliensis (Mold) ATCC16404

The standard Bacterial and Fungal inoculum pools were prepared atstrengths of 10⁸ CFU/mL and inoculated at strengths of 10⁶ CFU/mL intoseparate vials of the samples on Day 0 (the beginning of Inoculation I)and then prepared anew and reinoculated into the same vials on Day 7(the beginning of Inoculation II).

After inoculation sample vials were incubated at 25° C. The samples wererun in triplicate. Bacterial recovery was determined by plating 100 μLof the sample onto Tryptic Soy Agar and using the following ratingssystem in Table 3 to assign the appropriate score. Fungal recovery wasdetermined by the same method and was plated onto Potato Dextrose Agar.

Results and Discussion:

Based on the following results seen in Table 2 below, all providedsamples of composition 2, either preserved with 200 ppm of activebenzisothiazolinone or unpreserved, effectively controlled against bothbacterial and fungal contamination in accordance with the criteriadescribed above (U.S. Pharmacopeia XXI <51>).
